Researchers have engineered bendable batteries that can run on body-inspired liquids such as normal IV saline solution and cell-culture medium. The authors designed alternatives to lithium-ion batteries by focusing on the mechanical-stress demands of wearable electronics such as smartwatches and the safety requirements of implantable electronics.
